Just a heads-up, because you're new: We have to deal with folks rather frequently who try to get us to solve problems and homework for them. We don't really like that. If you want to talk about cryptograms and random thoughts that cross your mind, we're generally friendly people.

Hi, im a new here, because this question is really too hard for me to solve it, even have no idea to start. It is a question from my teacher's example list, just want to find anyway or ideas that i could use to solve any other similar question like this. if you can help me some, many thanks

Tshan,
Lurker is quite right that this is NOT a simple substitution code. I seriously doubt that any of us could help you, even if we wanted to.
What teacher?? What class?
We're mostly a bunch of pretty nice folks who love to help when we can, but that's not always possible.

hi, thanks for replying. it is a college Applied Math course. I think the code start with a double "MM", which means there must be a space between 2 Ms, like M MCBT...and MCBT... should be a word after M, I take a guess that M is more like an "I"?? because it could not be an "A"?? so it will be like "I" "I"CBT...otherwise i cant think out anything else... it is a really hard question. if you guys can help me or any suggestions. thanks

i was just wonder why u reply this post if you are so rude and unhappy???
am i bothering you something??
you do not have to reply if you do not like it. you do not lose anything, and i do not gain any profit cause this post.

Yes, this is way beyond what happens here at cryptograms.org. There are patterns here however that are interesting:

- that E at the end is the only "word" that is not 5 letters long
- there are double letters all over this thing

So, perhaps you are right, that the double letters somehow signify a space, rather than the actual spaces.... Or, more likely, something else....

Because, there are not enough double letters, so that if that were the case, this phrase would have some awfully long words in them....

It could also be backwards, as it is extremely unusual for any phrase in English to end with a single letter.

Also, this may not have anything to do with common language, and have more to do with mathematics....

Whatever the case, I just now saw this thread, and missed the removed comment. But FYI I've seen in the past month or so, 2 posts from new users who were just trying to make themselves feel smarter it seems, so you may have experienced some backlash based on those previous threads.

But, if you'd like to exercise pattern recognition and perhaps come across some interesting quotes, try some of the cryptos here - I've found it quite amusing, if not addicting!

Another oddity... All of the letters of the alphabet are used. It could be that there is a null letter, or two. If you knew which letters were meaningless and removed them from the code it could still possibly be a substitution cipher... grouped in 5s to make it harder for humans to crack?

Since the cypher ends in a single letter, try working it backwards.
Remove all double letters that appear ...either just use the letter once
or remove them completely.
ie...the fifth cypher is tyccq
remove the two c's
either replace it with just one
or take them out completely
reverse the order

this is just a guess. do that with every double letter in each occurrence.
reverse the cypher so it starts with e..
then use this...

Code:

simply enter the cipher and try to see if it can help you.
or try it with the idea you had with the mmbct where there is a space between
double letters.

cypher4u is right all the letters are used and its five letters per "word"
try every fifth word.
i suspect there are null letters in there, im assuming its the double letter instances.
another way to look at it would be to find the most common letter used
count each letter ..find how many times each letter is used and look for a pattern.
the solve could be in the pattern not the letters themselves.
i dont know if this helps but its better than a grouchy response.
good luck.
